Weight Stigma

The fashion industry has for a long time produced images of mostly women and men that did not correspond to the normal weight distribution of people. Skinny models were present across all media. The so-called social media of today amplify this trend further. The “Barbie hype” has reinforced the idea of low weight as a socially desirable norm. In scientific research the term coined for this phenomenon is “internalized weight stigma” (IWS). A study shows (Highes et al. 2024) it affects more women than men and more people who are described as socioeconomically disadvantaged adults. Pressure to lose weight originates from multiple sources and social media platforms have given rise to bullying. A major outcome of IWS is eating disorders as eating is often wrongly associated to be the only cause of higher weight. It is not. Many other factors contribute to the actual weight of a person. Even the overuse of the body mass index (BMI) as short hand version to define overweight or obesity is misleading for persons with strong muscles. Just fixing on one parameter of body shape or weight tends to reinforce weight stigma. “Keep walking” and a regular healthy diet, this avoids to internalize a weight stigma. Exercise is fun, the more you do it in a group, the easier it is to get going regularly. We ought to keep trying and eventually it will become a routine.

Screening Paradoxon

In the field of public health the screening paradoxon is a well-known feature of large scale programs to check for and contain the large increases in cancer among populations. A recent medical study underscores the necessity to curtail the screening paradox in Europe. The screening paradoxon is defined as “the underuse of screening by those with unhealthy lifestyles and high risks”. The opposite cases, “the overuse of screening by those with healthy lifestyles and low risks” only cause a problem for the costs of the health system as those unlikely of attaining a form of cancer make extensive use of screening. In terms of social inequality we have to be concerned about both ends of these distributions. The publicly available screening programs are skewed towards the higher educated with risk awareness as well as healthy life styles. More of them participate in screening. The other distribution of actual risks and detection of cancer is skewed towards the other end of the risk distribution. The 2 probability distributions overlap to an extent that is most likely co-determined by cultural factors like general attitudes towards prevention.
With the increase in cancer rates generally and due to demographic aging of societies, we shall need to target our resources devoted to health more precisely rather than spending too much on screening of people with very low risks. Increasing the duration between screenings might not impede detection rates of those with healthy lifestyles, but could allow to devote more resources to those people who are hard to reach by screening programs so far. Evaluations of such programs are necessary to judge the need for more targeted programs.(Image own representation inspired by Ola et al. 2024)

Barbie Chemical

Chemistry is sometimes perceived to be uninteresting, but only until you realize it might be beneficial to know more about some underlying chemical processes. The Royal Society of Chemistry has finally found a topic in chemistry to give chemistry a popular push. The Barbie hype is far from over as we all learned in the recent past. Now conservationists have found a topic with chemical processes involved to demonstrate the usefulness of chemistry knowledge for the conservation of your treasures or collections of plastic dolls or puppets in general. Most plastics PVC was not intended to last, but the deteriorated forms have a long lasting effect in form of PVAS or microplastics. So aging research has reached popular concerns like the aging of Barbie, who is believed to be “forever young”.

Photos Exhibit

Our usual expectation of an exhibition of photography is to look at photos at a wall. Sometimes there is more it. The Exhibition Space at the “Haus am Kleistpark” features Michael Schäfer who attempts to go a bit beyond these traditional forms. In the works of photo cubes on water surfaces “2021_57”, or a dice floating on the waves of oceans, the video representation of his photographs takes the assembled images beyond their flat 2D surface. However, the 2D representation is at the origin, then transformed into a 3D dice, which then is animated as a 4D format. Moving beyond the flat screen image takes photography into the 21st century.
His work “Les acteurs 1-26” from 2007 is shown at the entry hall of the exhibition. It shows pupils of a class at an elite school who deem themselves in leadership roles in the near future. Is it acting? Is it projection into a future role they are likely to take on. They represent stereotypes, of course, but some are pretty convincing in these roles already. Some others still seem to reflect on what they are doing there. Even acting these roles, they are aware of the meaning of social rank and class in society. Without having read the sociologist Bourdieu, all are aware of the fine, little elements of distinction as they have evolved over time. We could teach an interesting sociology class in this exhibition.

Science Politics

We tend to believe that science is independent of politics. Even if the individual scientist does research and studies free of immediate political influences, there are many ways in which politics has an impact on science. Sociologists refer to Max Weber as a prominent figure in the “Werturteilsstreit” that claimed the need for science to be conducted beyond political interference. Karl Popper is another reference in this respect who proposed the positive science approach which starts from theory, hypotheses and testing in the sense of identifying false statements, hypotheses and underlying theories. Modern science is also linked to publications of results. This has become an industry of its own and it is sometimes quite surprising to see the lengthy delays that scientific results get published. One example, Jackie G. Schneider and Julia Macdonald (2024) had to wait 3 years until their paper finally appeared in print in a scientific journal. This paper was received by the Journal in February 2021 and published only in 2024 in the 2nd issue of the journal but online in January 2023! Reports in Nature on difficulties of Indian, African and Chinese scientists to get their work done and published are alarming as well. Further regionalization and departmentalization work against the fundamental principles of independent science and scientists. It is a big issue of international cooperation as well.

May 1st

More people take to the streets on the 1st of May in Germany. The costs-of-living crisis with high inflation has increased the claims for pay rises for workers and adjusted wages for employees. We all have observed “greedflation”, i.e. excessive company profits in several sectors. Additionally, “shrinkflation” has affected consumers in their daily shopping experience. Political efforts to curb inflation have taken a long time to come about and most initiatives have ended already (Energy sector). This spurred a new drive for trade unions to come out in huge numbers to protest and claim adequate wage increases to cover the increased costs of living. In Germany the DGB informed on the annual 1st of May demonstrations across the country about a strong new entry movement of members of 400.000 persons. It is higher than the loss of members of the large baby boomer cohorts who retire.
Through a broad and engaged membership the pressure on higher wage settlements will persist. Companies have used the crises to generate extra profits. It is only fair that those employees who largely contribute to the success of a company will claim their share as well.
For society as a whole it is important to consider that the discrepancy between managerial pay and shop floor wages do not increase further. The social fabric of societies is in danger if perceived injustices grow. More radical forces can all to easily exploit this causing a severe danger for democracies. Meeting people on the 1st of May and joining forces across sectors and trades ensures that a society continues to build and rely on solidarity. High inflation times are a great reminder of the economic basics of societies in history as well as today.

Find Trust

Societies have different levels of trust. Trust in politicians or political institutions has been researched a lot. Another example of trust is related to things lost and found. Losing an item on a train or a mobile phone somewhere are severe tests of the level of trust in a society. How likely is it that the item is going to be found and returned to you. We usually estimate the probability of the return of items as being rather low. The more we are surprised to find out that there are thousands of items found and returned. The Deutsche Bahn has a special service in operation to take care of lost items. Additionally, there are auctions of items found but nobody claimed the ownership of it in the following months. Not giving up on a lost item is the first step to find it again. It would be a nice test whether in high trust societies it is more likely to find something lost. If you have a higher trust that items will be returned you are also more likely to make the effort to claim the item back.

Comparative Advantage

In economics all students go through the calculus of comparative advantage. People, regions or whole countries tend to apply comparative advantage to their production systems and ensuing internal or external trade. The basic  rationale developed by David Ricardo has not changed that much over 200 years. The fields of application, however, are continuously expanded. Lindsay and Gartzke (2020) have applied the comparative advantage rationale to military strategy. The paper quotes 26 times Clausewitz and demonstrates the links of strategy to the basic economic and social rationale of comparative advantage. It is the politics of production that even the presence of trade may override the rationale of comparative advantage to favour local production of “operational domains” or military equipment.
In Russia’s aggression and war against Ukraine own production and trading of weapons has returned to the forefront of the concerns. In addition to the production of ammunition, the provision of drones has dominated the international arms trade related to the Russian aggression. Resources and time for production are additional factors that have an impact on availability of weapons at the right time at the right place and with the sufficiently trained persons to operate them.
The strategies that cross domains or combine domains seem the most promising. The careful analysis of your own comparative advantages or disadvantages needs to be the basis of any strategic decisions. This has been known for 2 centuries at least and is still valid in many fields of application. Additional considerations for “home production” might add to the complexity of the issue. Sustainability has also found its way into the field of comparative advantage at last. This may alter the analysis of comparative advantage of operational domains as well. Lots of unresolved puzzles still around. It will need years to sort this out despite the urgency of the Russian aggression on Ukraine.(Image: AI Copilot.2024-4-30 2 political leaders deal weapons. One has a comparative advantage in ships. The other one has a comparative advantage in aircrafts. they deal together)

AI Disruption

Many scientists started to question the disruptive potential of AI in, for example, the military’s domain. The Journal of Strategic Studies featured 3 papers on AI and autonomous systems more generally. The major argument by Anthony King is the reliance of autonomous systems on other systems mainly human operators even in the background to get these systems off the ground and maybe back again. Not only logistic support but also satellite communication is needed to guide and protect the operations. In quoting Clausewitz, Anthony King stated that war is a “collision of two living forces”. Strategy and counter-strategy will co-evolve as will attack and defence.
Jackie G. Schneider and Julia Macdonald (2024) advocate the use of autonomous and unmanned systems for their cost effectiveness. Economic costs as well as political costs are lower for these new strategic weapons. Mass fire power from swarms of drones is much cheaper than nuclear warheads and the home electorate is assumed to be more willing to accept and support limited and more precisely targeted unmanned missions. The disruption potential of AI is huge but it is most likely an addition to the arsenals than replacing them.

Time Perception

There are many different angles from which to look at time. Of course, we all do it several times a day or during boring meetings. The study by Ma, Cameron and Wiener (2024) highlights the bi-directional link of perceived time and memorability. Visual stimuli alter our perception of time. Watching a video we all make the experience that the perceived length of the time spent watching varies according to content and maybe only the cutting technique applied to shorten the perceived length. Similarly it has been demonstrated that looking for longer at an image and grasp the meaning or implicit story we tend to remember the image for longer. In courts it is a usual procedure to question the memory capacity of persons and the sources of bias. The study by Ma et al. demonstrates the impact of the size of the scene, how cluttered it is and aspects of memorability in visual perception. Our memories are co-determined by these factors. The other direction of causality i.e. that memorability determines the time perception seems equally at work. This apparent undetermined element, so far, calls for additional care when analyzing recall from memory. Memory is not only selective in terms of content, it also is subject to the impact of all sorts of visual stimuli.
Time can be many things. For humans it is everything but exact. In science we measure time with ever more exactitude and try to standardize time on the moon now. In addition to exact time, humans have perceived time and subjective versions and even concepts of time. About time to take time more seriously.
